Andrew, IMO you can drop this and the const cleanups from -mm tree.
Jan, nearly all code in:
drivers/acpi/*/*.[hc]
is part of ACPICA. This currently still is (may change) an Intel
internal repository which gets synced to several OS implementations,
also Linux. __init does not exist there (yet).
Also the const changes may be a bit of a pain -> this is what Robert
meant with as long as it won't end in a chain of const cleanups :)
The whole code gets style cleaned up through Lindent and manually to
half way fit to the Linux kernel style when things get merged.
Currently Robert has to readjust this to ACPICA coding style by hand
and merge it into the internal Intel repository. Len has to pick it up
somewhat later and merge it back to the Linux kernel...
Therefore I expect for cleanup patches (this one is on the edge, but I
could understand Intel if they hold it off) the best is to wait until
Intel publishs ACPICA as CVS or whatever repository on their
lesswatts.org site.
Then it is at least only half of the merging work and this half a bit
automated with Lindent...
ACPICA is packaged on SUSE in the pmtools package, it's rather new, but
it's not the very latest version, waiting for a revision control system
is worth it, before ending up in manual fiddling...
